Stark photos of people arrested before and after becoming addicted to drugs have been released as a warning about the physical effects on users.
Rehabilitation group Rehabs compiled the photos to raise awareness of what can happen when addiction takes hold. In the US alone, more than 1.6 million Americans were arrested on drug charges in 2010.
Around 4.5 million people in the US were classified as abusing or being dependent on illicit drugs in 2012, according to a government survey.
The people in the photos are users of cocaine, heroin or oxycodone – a prescription opioid. All can change a person’s physical appearance – which is documented candidly through police mug shots.
